Application filed April 12,

This invention relates to filling re lenishing looms and is more particularly irected to the thread control with'bobbin cleaning attachment for withdrawing the thread from the shuttle box on replenishment of filling and cleaning the bobbin of waste yarn.

In that type of filling replenishing looms wherein replenishment of filling is ett'ected by a change in the filling carrier or bobbin in the shuttle, it is desirable to withdraw the filling end of the outgoing filling carrier from the shuttle to prevent such end being carried into the shed and to clean the bobbin of waste yarn thereupon after the bobbin has been ejected from the shuttle.

An important feature of the present invention therefore consists in an attachment for filling replenishing looms whereby the filling end extending into the shuttle from the ejected filling carrier is withdrawn therefrom and the waste filling upon the filling carrier or bobbin is unwound or withdrawn therefrom during the operation of the loom following replenishment.

In accordance with the prcscnt invention the filling carrier which is ejected from the shuttle on replenishment of filling is discharged into a bobbin receiver and the end of the filling leading from the ejected carrier is withdrawn from the shuttle and un wound from the ejected filling carrier or bobbin.

The invention and new combination of parts and novel features thereof will best be made clear from the following description and the accompanying drawings of one good form thereof.

In the drawings:

Fig. 1 is a perspective view of portions of a loom having the present invention applied thereto and showing some of the parts broken away;

Fig. 2 is a transverse section through the bobbin receiver and the parts associated therewith, and showing the bobbin positioned for removal of filling leading therefrom;

Fig. 3 is a section on the line 3--3 of Fig. 2; and

Fig. 4 is an enlarged sectional detail showing the clutch connection between the bobbin cleaning device and its actuating shaft.

The loom frame 1 may be of usual construction and rising from the breast beam 2 is the hopper or magazine stand 3 contain- 1827. Serial No. 183,046.

ing a 'series of filling carriers or bobbins 4 supplied with filling. Extending laterally from the feeler stand is the stud or dead shaft 5 on which is mounted the transferrer 6, the downwardly extending arm 7 of which is associated with the do 8 which on detection of substantial exhaustlon of fillin 1n the shuttle is positioned to be engaged by a bunter on the lay to actuate the transferrer, as usual in this general character of loom.

Secured to the loom frame 1 is a bracket 9 on which is supported a bobbin receiver 10 into which the ejected filling carrier is thrown on replenishment of filling. The bobbin receiver 10 has an 0 en bottom 11 below which is located the bobbin can 12 for receiving the cleaned bobbins, in a manner later to be described.

Extending transversely of the bobbin receiver 10 is the bobbin cleaner and filling end withdrawing device. As indicated in the present instance of the invention, the bobbin cleaner comprises a shaft 13, one end of which extends laterally through the side of the bobbin receiver 10, and is provided with a pulley 14 by which the bobbin cleaner may e given rotary movement from some going partof the loom. As shown, the bobbin cleaner shaft 13 is driven by a belt 15 which passes around a pulley 16 mounted on the cam shaft 17 and preferabl though not necessarily, formed as part 0 the hub portion of the pick cam 18, the construction being) such that the bobbin cleaner shaft 13 will e continuously rotated during the loom operation.

Mounted on the shaft 13 is the bobbin cleaner 19 which may be of general cylindrical form and have a roughened exterior surface, shown in the present instance as provided by wire teeth 20. The bobbin cleaner 19 is operatively associated with the shaft 13 by means of a clutch which, as shown, comprises a series of yieldable fingers 21, Fig. 4, embraced by a spring 22 and adapted to engage the end portion 23 of the bobbin cleaner 19, so that on rotary movement of the shaft 13 the bobbin cleaner will be rotated.

The bobbin cleaner 19 extends through the sides of the bobbin receiver 10 and in order to confine the thread or yarn between the sides of the bobbin receiver, guards 24 and 25 are preferably employed, the guard 24 substantially enclosing the clutch mecha nism between the shaft 13 and the bobbin cleaner 19, as indicated more clearly in Fig. 4.

Mounted in the bobbin receiver 10 below the bobbin cleaner 19 is the bobbin positioning device having compartments, each of which is adapted to receive a bobbin to be cleaned and retain it in bobbin cleaning position, so that the bobbin may be cleaned of waste thread or am while separated from bobbins previous y cleaned.

The bobbin cleaning device comprises a shaft 26 extending transversely of the bobbin receiver below the bobbin cleaner 19 and may be conveniently journalled in the side portions of the bobbin receiver, as indicated at 2 Extending radially from the shaft 26 are the wing portions 28 between each of which is formed a compartment for receiving a bobbin to be cleaned and positioning the bobbin for cleaning purposes.

7 In the present instance of the invention,

the wings 28 are mounted on a sleeve 29 secured to the shaft 26 so that on rotation of the shaft 26 the bobbin positioning device may be moved to positively discharge a cleaned bobbin from one compartment and position another compartment for the reception of the next bobbin to be cleaned following replenishment of filling.

One end of the shaft 26 extends beyond the side portion of the bobbin cleaner, as indicated in Figs. 1 and 2, and means are provided for imparting to the bobbin positioning device a step-by-step rotary movement on each successive replenishment of filling, to positively move the bobbin previously positloned for cleaning purposes and present another compartment for the reception of the next bobbin to be cleaned.

As one good form of means to this end, the shaft 26 is provided with a toothed wheel or ratchet 30, the teeth 31 of which are ada ted to be engaged by an operating pawl 32 aving a tooth 33, so that on endwise movement of the pawl 32 the bobbin positioning device will be given its rotary movement.

Mounted on the loom frame is the transverse or change shaft 34 having depending receiver 10, with the trailing end a of the waste thread or yarn thereon extending over and in contact with the bobbin cleaner 19, and to facilitate movement of the ejected filling carrier into the compartment of the bobbin positioning device, the bobbin receiver 10 is provided with a deflector 37, the lower end portion 38 of which is closely adjacent to one side of the compartment positioned for the reception of the ejected filling carrier or bobbin. The deflector 37, in the present instance of the invention, maybe conveniently formed of metal and have a bend 39 to engage a dead shaft or pin 40 extending transversely of the bobbin receiver, and in order to maintain the deflector 37 in its desired position and yet permit yielding movement thereof, the deflector 37 'below the bend 39 is provided with a yielding stop 41 which normally rests upon the side of the bobbin receiver 10, the construction being such that the ejected filling carrier will be thrown into the bobbin receiver, engage the deflector 37 and be by it directed into the compartment of the bobbin positioning device, as indicated in Fig. 3. so that the trailing end a leading from the waste thread or yarn on the bobbin will engage the bobbin cleaning device 19 and be by it unwound from the bobbin positioned by the bobbin positioning device.

When filling replenishment is being effected and a discharged bobbin is thrown from the shuttle, it is desirable that the end leading from the ejected filling carrier or bobbin shall be removed from the shuttle eye and shuttle box to thereby prevent the end of the filling being drawn into the shed, and in connection with the bobbin cleaning ,device the present invention provides means for withdrawing the end from the shuttle eye and shuttle box so that said end without breakage may be wound upon the bobbin cleaning device as the bobbin is being cleaned.

The thread controller for effecting the above purpose may be of any usual type, butinasmuch as the end of filling that is with-f drawn'froln the shuttle eye may extend over a part of the said controller and engage the bobbin cleaning device, a loop may be formed in the end of the filling above the bobbin cleaning device, and in accordance with the present invention, provision is made for the disengagement of the said loop from the thread controller in case of such contingency.

As hereinbefore noted, the thread con troller for withdrawing the end of filling from the shuttle box and shuttle may be of any appropriate character, but in accordance with the present invention, the thread engaging member of the said controller is extended laterally and downwardly so that in case of the formation of a loop over the said member of the controller, the action of the bobbin cleaner upon both parts of the thread will cause the loop to slip downwardly over the end of the laterally and downwardly extending member of the thread controller.

As shown in the the present instance of the invention, the thread controller comprises a sleeve 42 which is connected to the hub portion 43 of the transferrer, and such sleeve 42 has a downwardly extendin arm 44 carrying a in 45 connected by a link 46 to a carrier 4 in which is mounted for movement towards and from the front of the loom a slide 48. A spring 49 normally acts upon the slide 48 to maintain it in rearward position. Pivotally mounted at 50 on the slide 49 is the laterally and downwardly extending filling engaging member 51, which acts to permit the loop of thread which may be formed thereon to slide downwardly and over the end of the member 51 should both ortions of the thread be engaged by the bobbin cleaning device 19.

It is sometimes desirable to impart a frontward movement to the filling engaging member 51 of the controller on replenishment of filling to insure withdrawal of the filling from the shuttle and shuttle box, and as will be noted from the construction described, the downward movement of the transferrer will efiect frontward movement of the controller to withdraw the filling end from the shuttle and shuttle box. The slide 48 is provided with an opening 52 which engages a guide 53 in the carrier 47 in order to direct its movement towards and from the front of the loom. Should the filling engaging member 51 contact with the lay or be otherwise engaged during the loom operation, the spring 49 will permit a frontward yielding movement of the filling engaging member 51 which ma also pivot around its connection 50 with tli e slide 48.

During weaving operation the filling engaging member 51 is retained in position such that an ejected filling carrier will pass frontwardl thereof on replenishment of filling, and tlie frontward movement of the filling engaging member will whip the filling from the shuttle and shuttle box. When the ejected filling carrier is received into the bobbin receiver 10, the trailing end of thread a will be positioned for engagement with the bobbin cleaner 19 when the ejected filling carrier has been received into the compartment of the bobbin positioning device, so that both ends of the thread-that extending upwardly to the engaging member 51 and that extending downwardly to the bobbin positioned by the compartment of the bObblIl positioning device, will be simultaneously wound upon the bobbin cleaner 19, and should a loop of thread be formed about the thread enga in member 51 of the thread controller, t e 00p thereof will be moved downwardly on the laterally extending and inclined filling engaging memher until u on reaching the end thereof un-.

der the pul of the bobbin cleaner, it will be disengaged therefrom without breakage.

As hereinbefore described, the bobbin positioning device having the compartments for positioning a bobbin for cleaning purposes, is given a step movement on each replenishment of filling, to positively move the cleaned bobbin from its cleaning position and allow it to drop into the bobbin can beneath, and in order to prevent movement of? the bobbin positioning device during normal weaving operations, a lock is provided to prevent movement of the bobbin positionin device until call for replenishment of fil ing.

In the present instance of the invention, this lock is formed as a s ring arm 54 having an end portion whicii engages recesses formed in a locking member 55 secured for ,rotative movement to the bobbin positioning device, as indicated in Figs. 1 and 2. The weight of the pawl 32 resting on the ratchet wheel 30 also contributes to lock the bobbin positioning device from movement until call for replenishment of filling.

From the construction described it will be apparent that the present invention provides a simple and effective means for not only cleaning the waste yarn or thread from ejected filling carriers, but likewise to whip the end of thread from the shuttle and shuttle box and to wind such upwardly extending end onto the bobbin cleaner during the bobbin cleaning operation.

The bobbin positioning device with its compartments for positioning the bobbin for the cleaning operation and for thereafter positively removing the cleaned bobbin from bobbin cleaning position with the substitution of another compartment to receive the next bobbin to be cleaned, may be variously contrived, but the rotary winged positioning device forms a compact and readily adjustable means to this end.
